Fatigue has many causes: iron deficiency (#1 in women), B12 deficiency, hypothyroidism, poor sleep, blood sugar crashes, dehydration. Targeted nutrition addresses the root cause — don't just reach for caffeine.
Top Foods
| Food | Why It Helps | Best Timing |
|---|---|---|
| beef-liver | Nature's multivitamin: B12 (2471% DV), iron (27% DV), copper (1078% DV), folate (73% DV). Single most nutrient-dense energy food. B12 + iron = red blood cell production = oxygen transport. | 1x/week (50-100g). Don't exceed — vitamin A toxicity risk at >200g/week. |
| oats | Complex carbs + beta-glucan for sustained energy. B vitamins (thiamin, B5) for cellular energy production. Low GI (55) = no crash. | Breakfast |
| banana | Quick energy (23g carbs) + potassium for nerve function. B6 for neurotransmitter synthesis. Prebiotic fiber for gut-energy axis. | Pre-workout or morning |
| spinach | Iron (15% DV non-heme) + magnesium (19% DV) + folate (49% DV). Magnesium is required for ATP production (your cellular energy currency). | Daily, cooked |
| egg | Complete protein + B12 + choline. Tyrosine → dopamine (motivation neurotransmitter). B vitamins convert food → energy. | Breakfast |

🔍 Root Cause Checklist
- Iron deficiency? (heavy periods, pale skin, cold hands — check ferritin)
- B12 deficiency? (vegans, older adults, metformin users, tingling)
- Thyroid? (unexplained weight gain, cold intolerance, dry skin — check TSH)
- Sleep quality? (not just quantity — sleep apnea, alcohol before bed)
- Blood sugar? (crashing 2h after meals = reactive hypoglycemia)
